Since a view month my username was occationaly change from spotify from my real name to a anonymous bash of numbers. How can I can change back my username to normale, since my friends and social connections cant find me anymore!

Your friends can find you if you share with them a link to your profile. Here's how from the iPhone app: 1: Tap your profile picture in the top left

2: Tap the three dots in the top right.

3: either tap the huge icon with the Spotify code at the bottom, or tap share.

During signup, you were able to personalize your account by creating a profile name that’s displayed in the app. There’s no limitations to a profile name, so you were able to choose any name you like :)
